relates to airships, that is lighter-than-air craft, and has special reference to ships of this kind which have a rigid hull. Such rigid airships have gas cells within their hull and an outer cover stretched over it.

As these ships signed and constructed in constantly increasfrom year to year are deing dimensions, it is one object of my invention to provide and yet to make for a strong hull structure use'of every space available for inflating it with weight carrying lift-ing such as helium or hydrogen for example.

members and of cross members one within the other and connect them by force transmitting elements and the like, which both hull structures at such as struts, wires, cables are also adapted to hold the predetermined distance. These connecting elements, according to my invention,

ber-like spaces are structures, and into these chambers add1t1on al gas cells are tional airship.

In certain cases are so arranged that chamformed between both hull inserted which give addilift to the extremely strong rigid it may be advisable to provide different kinds of gas in the difierent gas cells.

For example the outer cells may be inflated with helium and the normal inner cells with hydrog compartments may others with other gas.

As fuel gas is tain compartments may tainers, whilst others may ing gas.

present invention,

en, or vice versa. Or special be filled with one gas and now used with airships cerserve as fuel gas conbe filled with lift- The manner of distributing the different airship is not subject of my but my new way of constructing the double hull structure opens new and advantageous possibilities for such distribution.

According to my invention the inner gas cells any also be in connection with one or more of the outer cells by means of connecting gas channels ply form bays or the outer cells may S1I11- forming part of the inner cells; or the outer cells may be interconnected 'in detail referring to the drawing which pepresents an example embodying my invenion.

Fig. 1 is a longitudinal vertical section through the hull of a rigid airship. Fig. 2 is a cross section taken on line 2-2 of Fig. l, but on an enlarged scale. Fig. 3 is a middle portion of the hull of the airship in longitudinal vertical section like Fig. 1, but on the same scale as Fig. 2.

In Fig. 1 merely the hull structure is pointed out, whereas Figures 2 and 3 show the gas cells also, partly broken up.

The outer hull is indicated at a, the inner one at b. There are connecting struts 0 and bracings m provided between them. d and.

6, respectively, are the longitudinalgirders of the outer and inner hull, respectively. The corresponding cross or ring girders are indicated by the letters f and g, respectively. Thus there are chambers provided between the two hulls into which gas cells h are inserted. The inner gas cells i are connected to the outer cells h by channels Z, whereas the outer cells themselves are inter-connected by channels Is.

In the example shown the two hulls are have a smaller distance in the variations will occur to those skilled in the art.

What I claim is:

1. A rigid airship comprising an outer hull structure, an inner hull structure, a structure connecting said outer hull to said inner hull, a as cell within said inner hull, two gas cells within the space between said outer hull and said inner hull, and connecting means between said latter two gas cells.

2. A rigid airship comprising an outer hull structure, an inner hull structure, a structure connecting said outer hull to said inner hull, a gas cell within said inner hull, a gas cell within the space between said outer hull and said inner hull, and connecting means between said two gas cells.

3. An airship including an independent hull structure comprising transversely extending polygonal rings secured together by longitudinally extending members, and a second independent hull structure surrounding the first and comprising transversely eXtending polygonal rings connected together by a second group of longitudinally extending nie11'1hers, neans connecting and holding the hull structures in spaced relation, gas cells within the first hull structure, and gas cells between the first and second hull structures.
